Title: Turn table platter for record player
Inventor: RIBERUTO MATSUSARERI
IPC: G11B3/58
Filed: 1982-08-24
Abstract: The applicant has devised a turntable platter for record players, consisting of two layers of glass and plastic lying one on top of the other. More precisely the plastic layer can be of a thermoplastic and/or thermosetting material such as polycarbonate, polyacrylic, polystyrene or otherwise. 
<??>The glass guarantees flatness, rigidity and pleasant appearance of the platter, such features not always being obtainable from the already known metal platters, while the plastic, for its part, guarantees the light weight associated with such material. 
<??>The glass-plastic combination in the turntable platter represents considerable progress in the particular industrial field as it guarantees reaching several results, including, most especially, the absorption of spurious vibrations, and secondly, optimum sound reproduction quality. 
<??>More especially, the first of these advantages is such that it is no longer necessary to use mats hitherto added to the already well known turntable platters. 
<??>The two glass (5) and plastic (2) layers can be joined together by means of adhesive (3) or pushed together along the edges; they can also be of different sizes and shapes. 
<??>It is advisable that the turntable platter obtained from said layers be provided with an upper layer (6), preferably less than one micron thick, of conductive material, either dielectric or metallic, in order to allow earthing the platter. 
<??>The outer rim of the platter is transparent in order to permit immediate visibility of the indicator lamp used by the stroboscopic device, hence it is not necessary to use an intermediate light deviating prism.

Title: Apparatus for detecting discontinuity of secondary winding of laminated type fly-back transformer
Inventor: WATAJIMA TOSHIHITO
IPC: G01R31/06
Filed: 1990-06-04
Abstract: PURPOSE:To accurately discriminate the half-discontinuity state of secondary winding not detectable heretofore from a normal state by magnifying the change of the slightly increased resistance value of the secondary winding to voltage drop to detect the same. CONSTITUTION:The irregularity of detected voltage, that is, that of forward voltage drop shows a tendency to suddenly become large in the vicinity where a current I exceeds 100 muA. With due regard to the current dependence of the irregularity of this forward voltage drop, the range of the constant current I is limited to 200 - 1000 muA. By this method, the effect of the irregularity of forward voltage drop on the discrimination accuracy of a half-discontinuity state can be avoided. By performing discrimination on the basis of detected voltage of a several 10V order to the forward voltage drop of several V, the effect of the forward voltage drop itself of a high voltage diode is also reduced and discrimination of high accuracy can be carried out.

Filed: 1989-06-09
Abstract: PURPOSE:To eliminate the need for providing the space equal to the length of an ununiform thickness regulating bolt to the lateral direction and to obtain a compact device by providing the ununiform thickness regulating bolt to the front face of a mold. CONSTITUTION:An ununiform thickness regulating pressor 6 connected to a regulating bolt is moved by operating the ununiform thickness regulating bolt 5 provided to the front face of a mold. An ununiform thickness regulating ring 4 brought into contact with the regulating pressor 6 in a tapered shape is moved to the arbitrary position of the central direction (the diagonal direction) of a stator mandrel 3 and fixed. The ununiform thickness is regulated by controlling the space between the stator 3 and the ring 4. The diameter of the ring 4 is properly regulated to 1-5mm larger than the diameter of the mandrel 3 being the stator to be used. The space between this mandrel 3 and the regulating ring must be changed by wall thickness of an obtained molded article and is regulated to about 0.5-2.5mm. Therefore the regulating rate of the space is regulated to + or -0.5/2-+ or -2.5/2mm in the diagonal direction.
